Suggest a method to purify a liquid which decomposes at its boiling point?

Answer: We have The given redox reaction can be represented as:  Cl2(g)  +  So2(aq)  +  Cl-(aq) +  So42-(aq) The oxidation half reaction is:  S+4O2(aq)  →  S+6O42-(aq) The oxidation number is balanced by adding two electrons as:  So2(aq)  → ...

In steam distillation, the organic liquid starts to boil when the sum of vapour pressure due to the organic liquid (p1) and the vapour pressure due to water (p2) becomes...

Alkanes experience inter-molecular Van der Waals forces. The stronger the force, the greater will be the boiling point of the alkane. As branching increases, the surface area of the molecule...

The temperature of a substance remains constant at its melting and boiling points untill all the substance melts or boils because, the heat supplied is continuously used up in changing...

Due to lowering in vapour pressure

(a) The solid exerts a force equal to its weight on the liquid. (b) The liquid exerts a force of buoyancy on the solid which is equal to the weight of...

(c) : According to Raoult’s law equimolal solutions of all the substances in the same solvent will show equal elevation in boiling points as well as equal depression in freezing...

(b) : For endothermic reaction, ΔH = +ve Now, ΔG = ΔH – TΔS For nonspontaneous reaction, ΔG should be positive Now ΔG is positive at low temperature if ΔH is positive. ΔG is negative...

(b) the forces between the molecules is stronger in solid than in liquids EXPLANATION:   The shape will change only if the molecules have some freedom of movement. In a solid the forces...

(c) decrease if it is taken partially out of the liquid (d) be in the vertically upward direction. EXPLANATION:   The force exerted by the liquid on the solid is equal to the volume...
